Abstract
Application of Risley prism pair for precise pointing a fixed point may be extended to optical tracking a moving target if a third prism is added to eliminate some of the adverse effect arisen from the blind zone and control singularity, which are inherent issues near both the central axis and the edge of the field-of-regard (abbreviated FOR) produced by matched Risley prism pair.
